While investigating what could be causing the Reply Tool to be taking an unexpectedly long time to save comments in T290514, @matmarex discovered that #discussiontools is not currently recording `save_success_timing` data [i]. This task involves the work with implementing the instrumentation necessary to log this data.
=== Requirements
- [ ] The instrumentation necessary for us to know how long after people attempt to save an edit using #discussiontools (Reply Tool or New Discussion Tool) said edit is either saved successfully (`saveReady`) or saved unsuccessfully (`saveFailure`) [ii]
=== Done
- [ ] Instrumentation is implemented that meets the requirements above
- [ ] QA (client- and/or DB-side) verifies data is being logged in ways that fulfills the requirements
- [ ] DiscussionTools documentation is updated to reflect this instrumentation change

i. I assume the `save_success_timing` is logged in [EditAttemptStep](https://meta.wikimedia.org/wiki/Schema:EditAttemptStep)
ii. I too am assuming these are the same events from [EditAttemptStep](https://meta.wikimedia.org/wiki/Schema:EditAttemptStep)
